It is obviously a budget thermal weapon sight, if you cannot afford a $0.50 cent piece of cloth to hang over it like the old fashioned cameras had, then you need a more expensive thermal weapon scope. Plus it has the photo and video built in too!

You can pick up a used android idiot phone for a song and a dance at a pawn shop and don't bother to get it hooked up to a cell carrier....or just pick up a real thermal scope at the pawn shop for a lot more coin...
